Does anyone have any experience with this one as a parent? Thanks.
Rob,
I have attempted to use Louis Jolliet in both directions. Although I do get the occasional OP hip from LJ, I never had any luck using it as a female. However, it does have viable pollen, although I have not used it extensively. It tends to suffer quite a bit of winter kill each year and the hybridizing season is pretty much over before I see a lot of bloom. I simply tend to forget about it–which could be a mistake.
I have two seedlings from 2001 that are a cross between Prairie Princess and Louis Jolliet. Both seedlings exhibit better-than-average disease resistance, and winter hardiness and vigor are better than either parent in my Zone 3 garden. I am pretty ruthless about discarding seedlings, but both of these plants keep surviving my culling efforts and remain to bloom another year. One is more upright in growth, while the other is more low-growing and spreading–like LJ, but much more vigorous than either parent. Both have copious amounts of early bloom with some repeat and are prolific hip producers. Last year I pooled OP seeds from these roses and kept about half a dozen seedlings. They are all a medium pink and vary from single to double. All but one seem to have better than average disease resistance, especially to blackspot. The one exception got slight mildew, not blackspot. I thought that there was a thread on the forum that mentioned that LJ has L83 in its background. That would account for the good disease resistance I see, since Prairie Princess was quite susceptible to blackspot in my yard (I have since discarded PP). I would be happy to share some OP hips with you from the Prairie Princess x Louis Jolliet crosses if you are interested. Interestingly, the new OP seedlings from this cross that are in my greenhouse now all seem to have inherited the tendency to produce many OP hips. They all tend to have the growth characteristics and foliage more typical of LJ than PP.
Let me know if you are interested in any hips.
Sincerely,
Julie
Julie,
Thank you for sharing your exerience with LJ. I do remember reading that LJ has L83 in its background and assumed that disease resistance would be better than average for seedlings depending on what the other parent was. I like your choice of Prairie Princess as the other parent and I’m sorry to hear that PP gets BS in your yard. When I grew it in northern Bucks County, PA, PP was disease free in my yard and suffered no die back.
I would welcome some OP hips if you have some to spare. If you like I could email you with my address. Thank you!

The Rose Registrations list in the October/November American Rose magazine includes “Darpellerin” (‘Cape Diamond’) hybridized by Christian Bedard (Weeks 2008). It’s classified as a Hybrid Kordesii, with mossy, fragrant buds, and medium pink flowers 8-10 cm in diameter, with intense fragrance. It’s claimed to be very disease-resistant (I’m still waiting for the first registration that claims “foliage highly susceptible to all diseases”). Repeat blooming is not claimed.
Parentage? Marie Victorin x Louis Jolliet
Bob,
Go ahead and e-mail me your address–I’ll be watching for it.

Julie,
I tried to email you several times through this forum and got a message that the email failed. I’m not sure why. Here is my email. rosebreeder@yahoo.com Could you email me and then I can send my address? Thank you!
Rob
Julie,
Ignore my last message. I see that you have already emailed me. lol Thank you!
Rob
Sorry Julie, I tried to respond to your email and got a message from a mail daemon that your email address wasn’t a valid address.

Thanks for the info on Darpellerin Peter. Given the parentage I wonder where the moss on the buds came from?? I look forward to when this one is available.
